What causes pressure ulcers?

Posted by

There are several reasons that can contribute to the cause of pressure ulcers also known as bed sores. One reason is pinching and constriction of blood vessels at pressure spots that cause lack of oxygen and nutrients to the skin and tissues in those areas. Another cause of bed sores comes from the friction of mattress against your skin. This comes from staying in one position for too long. You are at risk if you are bedridden, use a wheelchair, or are unable to change your position often. These types of pressure ulcers can cause serious infections and can be life-threatening. Pressure ulcers can definitely be a problem for elderly people and people living in nursing homes. Common ulcer sites include the back or sides of the head, rim of the ears, shoulders/shoulder blades, hips, lower back or tailbone, and heels, ankles, and skin behind the knees. Pressure ulcers have a variety of treatments. More serious sores are hard to heal, so early treatment is best.

Each individual cell of UltraForm pressure relieving products have low resistance, allowing them to “cradle” a bony area while the surrounding network of cells disperse the pressure.
